Whip In doesn't have it, Whole Foods has it from time to time, but they rotate beers all the time and they can't tell me when they'll have it, Waterloo restaurant has it on tap all the time but says they can't sell it to me by filling up my growler...anybody?

i emailed the PR person at the brewery, she responded quickly:
"Thanks for the inquiry. It is not legal in the state of Texas for any unlicensed entity (that would be you) to purchase beer or fill growlers at the place where the beer is manufactured. Have you tried Whip-In?"
